Extremophiles, and What They Mean For Life in Space

Extremophiles are organisms on Earth that thrive in extreme environment that most other organisms wouldn’t be able to survive in. They are found in places that at a glance, seem unlivable, places like inside volcanoes, or deep in the ocean under extreme pressures. So why do these extremophiles matter when thinking about space?
